The correct analogy is that of "A big greedy dog stealing away a bone from a smaller dog."

An ionic bond is a bond formed formed between a metallic atom and a non-metallic atom.

The metallic atom is electropositive while the non-metallic atom is electronegative. Therefore, the metallic atom donates or gives up its electrons to the non-metallic atom which accepts the electrons.

During the formation of chemical bonds, only valence or outermost shell electrons are involved.

Metallic atoms have few valence electrons (between 1 to 3 electrons) while non-metallic atoms have many valence electrons (between 5 to 7 electrons).

Therefore the analogy by the student of a big greedy dog stealing away a bone from a smaller dog is correct because the non-metallic atoms takes the few electrons of the metallic atom and add to the many electrons they already have during the formation of an ionic bond.

The ksp for silver sulfate (ag2so4) is 1. 2 ✕ 10-5. Calculate the solubility of silver sulfate in each of the following
Allisa [31]

For ksp of silver sulfate (ag2so4) at 1. 2 ✕ 10-5, the solubility of silver sulfate is mathematically given as

x = 5.26*10^{-4}

<h3>What is the solubility of silver sulfate in 0.15 M AgNO3?</h3>

Generally, the equation for the  Chemical reaction is mathematically given as

Ag2SO4 ⇄ 2Ag+  + SO4 2-

Therefore

Ksp = [Ag+ ]2 *[SO4 2-]

1.2*10-5 = ( 0.15 +2x)2*(x)

x = 5.26*10^{-4}

In conclusion, the solubility of silver sulfate is

x = 5.26*10^{-4}

A spectator ion is (Select all that apply.) a. an ionic component of a reactant that is unchanged by the reaction your eye, b. c
DENIUS [597]

Correct Question:

A spectator ion is (Select all that apply.)

- a piece of french fry contaminating the reaction mixture

- an ionic component of a reactant that is unchanged by the reaction

-in this experiment, nitrate ion

- your eye, carefully watching the progress of the reaction

Answer:

- an ionic component of a reactant that is unchanged by the reaction

Explanation:

A spectator ion is an ion that exists as a reactant and a product in a chemical equation. A spectator ion is one that exists in the same form on both the reactant and product sides of a chemical reaction.

Spectator ions are ions that are present in a solution but don't take part in the reaction. When reactants dissociate into ions, some of the ions may combine to form a new compound. The other ions don't take part in this chemical reaction and are therefore called spectator ions.

The correct option is therefore the option;

- an ionic component of a reactant that is unchanged by the reaction

anastassius [24]

Answer:

The range of [H⁺] is from 2.51 x 10⁻⁶ M to 6.31 x 10⁻⁶ M,

Explanation:

To answer this problem we need to keep in mind the <u>definition of pH</u>:

  • pH = -log [H⁺]

So now we <u>calculate [H⁺] using a pH value of 5.2 and of 5.6</u>:

  • 5.2 = -log [H⁺]

-5.2 = log [H⁺]

10^{-5.2} = [H⁺]

6.31 x 10⁻⁶ M = [H⁺]

  • 5.6 = -log [H⁺]

-5.6 = log [H⁺]

10^{-5.6} = [H⁺]

2.51 x 10⁻⁶ M = [H⁺]
